Choosing an interval is largely a trade-off between presenting too much information with a high number of intervals, or showing too little change between the intervals when a low number is selected.
选择间隔实际上是一种权衡：是使用较高的间隔值来呈现大量信息，还是使用较低的间隔值来显示非常少量的更改。

每周工作1小时，肯定不可能做好工作；每周工作168个小时——整整一周全天24小时工作——也并不合适。
